The blue background represents both our British heritage as well as our marine geography. The green represents NZ's clean, green branding and nature.
The fern also represents our beautiful native flora as well as being internationally represented by our proud sports teams and businesses.
The Kiwi logo represents New Zealanders. We are known internationally as 'Kiwis' and it represents us regardless of ethnicity or culture, united as one nation.
The Southern Cross reminds us of the old flag and includes the Maori red colours as well as remembering the celestial navigation they used in coming to NZ.
